We are going to start printing more waterbase/discharge and I was wondering if there were any recommendations for a good all around emulsion. We do small runs typically between 48-144 pieces. Thanks in advance for the help.
happy with aquasol hvp here. matsui wb inks cannot seem to put a dent in it. our wb flatstock inks do stress it out on longer runs using very thin stencils but it still does not break down, only gets a little damp/tacky on the substrate side. (which sucks for printing on paper) can anyone speak for this emulsions discharge performance though?I do keep diazo for it on hand that, soon as I catch a minute, I'm going to start using. although hv is a pure photo polymer the diazo strengthens it's water resistance. the reclaimable hardener is probably a good idea too. however the best practice with any emulsion for wb starts with a dry fresh screen, full exposure, complete drying again and a thorough post exposure. you probably know that part already.

I have lost dots and pieces of designs in the 75 piece range. That being said, I purchased some Murakami Hardener MS which is reclaimable and it is wonderful. Just spread some on the squeegee side of the screen with a paper towel and blow out the design with compressed air, let it dry for a few minutes, and print.No tacky emulsion, no worrying.All that being said, I have a sample gallon of Kiwo Discharge/One Coat that I'm going to start testing soon for solids content, exposure properties, and wb durability.
